Mark Lawson talks to the influential sculptor Sir Anthony Caro about his life and career in art. In this thoughtful interview Caro reflects on his time as Henry Moore's assistant, his groundbreaking shift from figurative to abstract sculpture, his position on public art and his dream of working 'until I drop'. Since his pioneering show at the Whitechapel London Gallery in 1963 Anthony Caro became recognised as one of the most important and prolific sculptors in the world. His innovative approach to scale, form and materials to 'expand the language of sculpture' has not only won him international plaudits but has revolutionised the field of three-dimensional art.
